- 17:12 Feature #213 (Closed): test-Normaliz1.C
- for Christof: could you design a simple test with known output for Normaliz in src/test/test-Normaliz1.C?
The old te... - 16:36 Feature #211: NBM: add SparsePolyRing as argument for ordering
- Eva and her colleagues will test the code over the next few days. If no problems arise, I'll close the issue.
- 16:30 Feature #211: NBM: add SparsePolyRing as argument for ordering
- Hacked Laura's code. It seems to work on some simple tests.
Code needs tidying, but that's low priority... - 15:24 Feature #211 (Closed): NBM: add SparsePolyRing as argument for ordering
- 16:19 Feature #209: ReadExpr: input polynomials in CoCoALib
- Here are some sample inputs (which we can use for testing):
* @- 1@ the same as @-1@
* @(-1)@ this is an expression,... - 15:39 Feature #209: ReadExpr: input polynomials in CoCoALib
- In the previous note I suggest that _erroneous but syntactically correct_ input is easy to handle. The case of _synt...
- 15:09 Feature #209: ReadExpr: input polynomials in CoCoALib
- The case of incorrect input which is syntactically correct seems to be easy:
* the input string is converted success... - 14:42 Feature #209: ReadExpr: input polynomials in CoCoALib
- We must decide how to handle white space inside RingElem inputs.
As a rule-of-thumb we should accept as input (at ... - 09:40 Feature #40: Squarefree factorization - Alessio d'Ali`
- Next meeting will be in September; exact day still to be decided.

- 15:35 Feature #209: ReadExpr: input polynomials in CoCoALib
- JAA thinks polynomial input should accept expressions built from integer constants, symbols (with integer constant in...

- 14:45 Feature #210: Normaliz: "double" cone for speed and safety
- Merged with code by C.Soeger for *NormalizComputation* (initialization from @map@, call from cocoa-5)
- 14:36 Feature #210 (Closed): Normaliz: "double" cone for speed and safety
- normaliz comutations using @long@ might fail and using @mpz@ will take 10 times as long.
The cone implementation i...

- 17:17 Feature #209 (Closed): ReadExpr: input polynomials in CoCoALib
- It would be nice if one could read polynomials from an input stream the way we write them, for example as...

- 15:49 Feature #40: Squarefree factorization - Alessio d'Ali`
- Alessio has added some paragraphs about primitivization, including examples to show that Bernardin's algorithm does n...

- 15:10 Feature #206: Matrix equation solving: LinKer
- Added *LinKer* to CoCoA-5 and test.
Added test for CoCoAlib (added into ex-matrix3, written for _brother function_... - 10:17 Feature #206: Matrix equation solving: LinKer
- Written *LinKerByGauss* for matrices with entries in a field.
The code uses *RankAndGauss(M, ncols)* which compute... - 09:40 Feature #206 (In Progress): Matrix equation solving: LinKer
- find all solutions M*x = 0

- 17:59 Bug #149: Makefile dependencies
- another possibility would be to check in (and distribute) @Makefile_dependencies@ without external libraries (_i.e._ ...
- 11:14 Feature #203: Function to get the Hilbert Polynomial ring from GlobalManager
- Currently it is available calling the function...
- 10:40 Feature #30 (Closed): SwapRows, Cols
- 10:11 Bug #85 (Closed): QuotientRing problem
- Now it works. I can't remember fixing it and how, but obviously someone did...
- 09:49 Support #205 (New): Example for change of coordinates with coeffs in a matrix
- Add to *ex-RingHom3* an example for a change like *x --> A*x*

- 18:33 Feature #202: MatrixView/function for viewing a single row or column (RowMat, ColMat)
- another proposal...
- 10:17 Feature #202 (Closed): MatrixView/function for viewing a single row or column (RowMat, ColMat)
- We should make a special view for a row or column since the C++/STL for calling *submat* is so bad (vector containing...
- 11:20 Feature #203 (Closed): Function to get the Hilbert Polynomial ring from GlobalManager
- The function *MakeGlobalHPPowerList(const DenseUPolyRing& P)* in GlobalManager.C creates a list of polynomials.
Its ...
